WELLINGTON P. DOLLOFF, OF PROVIDENCE, RHODE ISLAND.

BUTTON.

SPECIFICATION forming part of Letters Patent No. 245,358, dated August 9, 1881.

Application filed June 14, 1881.

To all whom it may concern Be it known that I, WELLINGTON P. DoL- LOFF, of Providence, in the State of Rhode Island, have invented an Improvement in Buttons, of which the following is a specification.

My invention relates to that class of buttons where the shoe is pivoted to the end of the post, so that the shoe may be turned over to one side against the side of the post for the purpose of insertion or removal from the button-hole; and it consists in the improved construction of the joint between the post and shoe, and of the spring which serves to operate the shoe.

Figure 1 represents a side elevation of the head of the button and a central vertical section of the shoe. Fig. 2 represents a side elevation, showing; a plan view of the shoe as turned to the side of the post for passing through the button-hole. Fig. 3 represents a plan view, and Fig. 4 an edge view, of a thin disk of sheet metal employed to cover the spring. Fig. 5 represents an edge view, and Fig. 6 a plan view, of the spring. Fig. 7 represents a side elevation, and Fig. 8 an edge view, of a post made of wire, as adapted to my improvement. Fig. 9 is an edge view, and Fig. 10 a side elevation, of the post shown in Figs. 1 and 2.

In the drawings, A is the head of the button B, the post, which may be eithercut from a plate of sheet metal, with an opening, I), as shown in Fig. 10, or made of wire, as shown in Figs. 7 and 8.

G is the spring, made of sheet-steel, cut out in disk form, and having the diametrically-opposite notches c 0 cutfrom its edge, in order to provide for the reception of the ends of the bridge E. From the bottom of one of the notches c is struck up the tongue 0, having the same width as the notches 0 c, and extending to past the center of the disk, or to near the opposite notch.

The spring covering-plate D is cut out, like the spring 0, with notches d d and tongue d, from a very thin plate of sheet metal, like Ger- (No model.)

man silver, and this plate serves to completely conceal the steel surface of the spring 0, and When inserted in the shoe, as shown in Fig. 1, comes between the lower end of the post and the spring, so that the lower end of the post does not come in contact with the surface of the steel spring.

The bridge E, which serves to secure the shoe to the post, is made from a narrow flat strip of metal, curved or indented transversely at the point e, to form the connecting-joint, and adapted to pass through the opening I) in the post B. The lower end of the post B is bent at a right angle, as shown in Figs. 1 and 8. The foot of the post will thus form a stop against the movement of the shoe in the wrong direction.

In putting the several parts of the button together the springC and springcovering-plate D are first placed within the rim of the shoecap F. The ends of the bridge E, when passed through the opening b in the post so that the cross-bar b enters the groove 0, are placed within the rim of the shoe-cap F, so as to enter the notches doin the covering-plate and spring. The rim of the shoe-cap is then closed down, securing the several parts firmly in place. The spring (J is thus completely covered by the plate D, which intervenes between the steel spring and footof the post B, and is made so thin that it does not materially affect the action of the spring.

I claim as my invention-- 1. In a button, the spring 0, provided with the notches 0 c and the tongue 0, in combination with the shoe-cap F and bridge E, for holding the post, substantially as described.

2. Ina button, the combination ot'the spring 0 with the thin flexible plate D, made to completely cover the surface of the spring and to intervene between the spring and the end of the post, substantially as described.
